Abstract (en)
[origin: WO2021249690A1] The invention relates to a feed unit (1) for a fuel cell system (31) for feeding and/or controlling a gaseous medium, in particular hydrogen, comprising a jet pump (4), which is driven by a propelling jet of a gaseous medium under pressure, an outlet of the feed unit being fluidically connected to an anode inlet (5) of a fuel cell (32). The jet pump (4) has an intake region (7), a mixing tube (9) and a diffuser region (11), and the gaseous medium flows through the jet pump in a flow direction (III) which runs parallel to a longitudinal axis (52) of the jet pump (4), and the diffuser region (11) is at least indirectly fluidically connected to the anode inlet (5) of a fuel cell (32). The jet pump (4) has a housing assembly (6), the housing assembly (6) having the components main body (8) and mixing tube insert (17), resulting in particular in a modular design of the jet pump (4).
